I'HIXING CART.

Application filed December binder, mix it with any desired ingredientsand dispense it in any desired amount and with comparative safety to theoperator who is handling it.

Although I accomplish these results by the particular combination ofstructure her ina-fter described, I do not wish to be limited to thespecific size or shape of its several parts, or to the usefulness whichI describe as its application in other branches of industry will beobvious to these skilled in those branches.

In the construction or repair of roads, pavements or other surfaceswhich are paved or otherwise constructed to resist wear, it is commonpractice to cement the cracks between the paving stones or blocks witl.what is called grout mixture, which is usually a mixture of sand andbitumen, and its application act-s not only to hold the blocks of thepaving material together, but also to protect the edges of the blocksfrom chipping away. The mixture being,

made in a suitable container, it is customary to stir the mixture with ahoe or stick and the operator has then carried the container to theposition where it was to be used. Then he has attempted to pour out thenecessary amount by tilting the container and the difiiculties anddangers of this old method have been first that the operator could notsupply a uniform quality, that it required much labor to carry thecontainer about, that the mixture did not remain uniform, and finallythat he was always in great danger of having the hot mixture splash onhim while mixing, or flow out in a too large quantity and burn his feet.The particular construction of my device eliminates all thesedifliculties and dangers as will be evidenced by reference to theaccompanying drawings and the following description of parts.

In the drawings:

Figure 1 is a side perspective view show- 10, 1924. Serial No. 755,047.

Figure 2 is a top view and Figure 3 is a side yiew of my anti-splashmixing and dispensing agitator.

Figure l is a side view of my flow control plate.

Figures 5 and 6 are sections of the trunaions sup aorting the tank onthe frame.

Figure 7 struction showing howt-he tank may be removed from the framefor convenience in shipping, and for replacement and repairs.

In the drawings, 1 is the mixing and dis pensing tank preferably ofsheet metaland is a side View of the frame con- I of U shape withaslight flare toward its M H dispensing end.- Mounted on the top frontportion of the tank is a flanged plate 2 with upward front 3 anddownwardback 4. In order to be able to adjust this plate for any desired amountof plated with a lower notched edge 7 is secured within the tank on eachside, and hooked bolts 9 passing through the plate 2 and provided withthumb nuts 8, hold the slidplate in a rigid position, so that a definiteflow of mixture from the kettle will result when th e'tank is tilted fordispensing.

The kettle is supported by trunnions 9 and 10. The construction of thetrunnion 10 for one side is slightly different from the construction ofthe trunnion for the other side. The trunnion preferably of the driveside is hollow and is provided with an agitatorshaft 11 passing throughit, with a packing nut 12 to prevent leakage of ma- On the shaft, heldin position between the two trunnions for purposes of agitatinganddispensing the material in the tank, I have provided an agitatorframewith radial arms 16 carrying blades 18 preferably riveted thereto byrivets 19, and collars 15 are attached to the end arms to mount theagitator frame on theshaft 11, where it is held by set screws 17. Theblades 18 are set at an angle as shown to avoid splashing portions'ofthe shaft where it has dispensing aperture, a

as the agitator is rotated. The particular construction of theseagitator arms serves atreble purpose of mixing the grout thor' oughly,and preventing splashing of the hot mixture at the point where theblades impinge into it and lastly of acting as scraper blades to pushout the last particles of mixture when the tank is being emptied.

I have found a simple means of turning the agitator by fastening asprocket wheel 20 to the exposed end of the agitator shaft and drivingit with a chain 21 and another sprocket 22 supported in the frame andpropelled by the attached handle It will be understood that the methodof revolving this sprocket is not a feature of my invention, theparticular method I have described being one simple and easy way ofaccomplishing my purpose which is to provide a means of agitating thetank which will be effective whether the tank is stationary in fillingposition, or being moved or being dispensed. It can be supplied with anauxiliary drive from the axle 24 with a clutch so that when the cart isbeing pushed it automatically will turn the agitator.

The cart is provided with carrying wheels 25. The frame of the cart ismade in two sections. The lower section comprises supporting legs 26 andaxle supports 27 for the carrying axle, suitably braced by the bar 26The upper section of the frame is eX- tended upwardly and rearwardl andcarries the pushing handle 29.

The frame for the cart is held rigid by gusset plates 28. There is apair of these plates on each side which are bolted to the upper ends ofthe bars 26 and 27, with ecges of the plates extending beyond the axlesupport 27 so as to leave a space between the plates, and U-shaped slotsrounded at the bottom are formed in the two plates, which slots registerand a semicircular notch is cut in the bar 27 to form a support for thetrunions 9 and 10. The side bars 28 which carry the push handle 29 arepivoted at 31 between the gusset plates and the handle being raised thebar on each side drops between the gusset plates and is bolted in place.The handle bars are formed with a semicircular notch 32- to form withthe base of the U-slots 1n the gusset plates a bearing for the trunnionsof the tank. By loosening the bolts the handle bars are swung into theposition shown by dotted lines in Figure 7 so that when desired thetrunnion of the tank will be released and the tank can be readily liftedout of the frame.

A plate 33 is hinged to the wheel axle and hangs in a substantiallyvertical positio and in contact with the ground to be held in fixedposition when the machine is stationary and to prevent the flow of anyhot material from the tank onto the operators feet, the plate beinghinged so that the cart can be pushed over uneven ground without foulingthe plate. It will be noted that in tilting the tank for dischargingpurposes the handle and frame of the cart stay in a fixed position. Thetank is held in a stationary position with reference to the frame by alock bar 3d pivoted with a rivet at 85 to the back support bar 28 and anotch 36 which allows the bar to engage the pin 37 fixed in the tank. Byraising the lock bar the groove comes out of engagement with the pin sothat the tank may be tilted for dispensing by the handle 38. When thetank is pulled back to the normal position the pin 37 slides along thelock bar 34- until it engages the notch 36 and automatically locksitself.

Having thus described the particular combination which 1 claim as newand desire to secure by Letters Patent, what I claim 1. In a device ofthe character specified, a framework with carrying wheels; a tankpivoted in said frame, a sliding plate mounted on the tank or regulatingthe discharge therefrom, and means for retaining said sliding plate infixed position.

2. In adevice of the character specified,

a framework with carrying wheels, a tank pivoted in said frame, asliding plate mounted on the tank for regulating the dischargetherefrom, and side plates with notches along the lower edge thereof andhook bolts passing througlrthe sliding plates to engage said notcheswith thumb nuts for tightening the same to hold the sliding plate infixed position.

3. In a device of the character specified, a framework with carryingwheels, a tank pivotally mounted thereon, an agitator in the tank,aslidably adjustable plate, whereby the fiow of material from the tankmay be regulated and a hinged bailie plate supported from the frameworkwhereby the operators feet are protected from material discharging fromthe tank.

4:. In a device of the character specified, a tank and a frame-workcomprising upper and lower framework members adapted to support thetank, the upper .irame-work members adapted to form a handle for thedevice, and said upper framework members demountably secured in saidlower members. 5. In a device of the character specified, a frameworkwith carrying wheels, a tank in ounted on the frame-work and a suspendedbaffle plate supported from the framework members to protect anoperators feet from material discharging from the tank.
